Here are the parameters: You live in North America. You have a Large ring M98K Standard length mauser with a 23 5/8" barrel. It has a pristeen bore. You can chamber for ANY 8MM chambering that will fit into the standard length magazine with no more modifications than some filing of the mag well and grinding some on the bolt stop. THAT MEANS YOU ARE LIMITED TO 30-06 LENGTH CARTRIDGES (3.340" COL) You may not replace the barrel, you may not lengthen the action. What 3.340" COL 8mm chambering (standard or wildcat) would you choose? My vote goes to the 8mm-06 Ackley Improved ------------------ | ||

Wildcat Junkie, I think you�re right when choosing the 8-06AI. The 8x64 has nearly the same prestanda, but the cases are hardly available. I think the only manufacturer of cases and ammo today is the Sellier and Bellot. Brenneke has also restarted some production, but it�s scarce and hard to get - and horribly expensive (www.brenneke.de). For the 8mm-06 you have all you need without difficulties - the 8x64 is next until obsolete. If you like metrics the 8x60 does the same job with about 20 fps slower bullet. RWS still makes it. But your own decision is the best: go with the 8mm-06 AI. Best regards, Fritz | |||

quote: And at an appalling price, too (incidentally, in the 8 x 60 S, the new DK bullet has succeeded the older H-Mantel bullet). However, case forming from common cases is almost as simple as with the 8 x 64 and 8mm-06, and the merits of the 8 x 64, the 8 x 60 and the 8mm-06 towards to the 8 x 57 are rather relative - a few m/s more, and a slightly lower trajectory. As you know, I have an 8 x 60 S and like it, but I would never claim that it could do many things the venerable 8 x 57 IS couldn't.

If I'm building a new rifle, 8mm/338 Win Mag (reamer available at www.reamerrentals.com). If I'm buying a rifle already assembled, 8x64S. But don't forget, it wasn't too long ago that most people would have voted that if you went too far out into the ocean, you would fall off the side of the Earth... | |||

One of the gents in the local gun club has a 8mm-338 wildcat. He asked to use my chronograph one day, and he and I were both impressed by the velocities he was getting (23" barrel). I don't know what his loads were, but he was only about 100 fps behind my 8mm Rem Mag with the same bullet weights. Incidentally, he also has two 9.3 wildcat mausers, one on the 338 case and one on the 300 Win Mag case. Lots of neat toys. Back to the question though, (and haven't we done this before?) within the parameters given the 8mm-06 AI would be my choice. FWIW - Dan | |||

quote: I see your point, Sam and Dan (or at least i believe I might). While European users might immediately think first of the 8 x 68 S (common and popular as it is), the .338 Win basic case has one big advantage - in spite of its silly and superfluous belt -: that its length of about 64 mms is still reconcilable with standard-length Mauser M 98 actions. I admit that is a significant and useful consideration. The heretic counter-question (why would one wildcat down a perfectly good .338 WinMag by one half millimeter ?) be better not asked, since the "8mm" was just the presupposition of this thread :-) Incidentally, a new German wildcat has emerged (concocted by my good acquaintance Lutz Moeller): the 8,5 x 64, based on a necked-down 9,3 x 64 basis case. Its advantages (and its edge over e.g. the well-known twenty-years old 8,5 x 63 Reb) are obvious; Lutz explains it in detail on his website. Performance on game apparently is very satisfactory.

My appologies for not clarifying that point sir. The 8x57js is an excellent cartridge when loaded to "adult" pressure levels as you prescribe. This thread is concerned with the option of rechambering only. It seems that mr carcano has come down from the mountain (on another thread) with the stone tablets that proclaim: Thou shalt not rechamber an 8x57 M98 Mauser to 8mm-06! Thou shalt rechamber to 8x64 only! If thee rechamber to 8mm-06 thou shalt commit blasphemy against the inviolable and sacrosanct 8x64! Thou shalt tremble in fear before the wildcat cartridge, it is the work of Satin! Thou shalt be "terminally stupid" if thee doth not heed the devine word of Saint carcano and followeth him to the promised land! GIVE ME A BREAK!!!!! Sam B: I like the idea of the 8mm/338 Win mag, I just am not thrilled with the useless belt taking up magazine space. How about an 8x68 shortened to 60mm with a 9mm long neck? Load it to 3.200" COL and chamber in a 48Yugo, or a standard length M98 with no mods to the magazine. Should come close to the 8mm/338 Win mag don't you think. ------------------ [This message has been edited by wildcat junkie (edited 02-02-2002).] [This message has been edited by wildcat junkie (edited 02-02-2002).] | |||

My vote goes 8mm-06 ackley improved. I can get once fired 30-06 brass for .04cents each if I wanted at the local range. (by the handfulls) into my bucket, If I wanted that is... The 8mmx64s has a longer neck... It would require .280 Remington brass. Not impossible, just impractical.... | |||
|
one of us |
quote: Not. Meaning, in a longer sentence, that it does not "require" .280 Rem or factory fresh 8 x 64 brass. You just once again disproved your own point. Well, why do you think that reloading manuals - as well as yours truly - point out that the 8 x 64 S can be simply reformed from many choices of existing brass, such as .30-06, .35 Whelen, .270, .280, 7 x 64 (this latter with a wee bit more work, including first-time fireforming) ? Because it is practical and feasible. And now to the length "problem". Apparently this is an issue that you are Okay, here I have a heap of once-fired fired .30-06 brass, fresh from the range. Just for the fun of it, I measured their case lengths. They are now all situated between 63,2 and 63,5 mms, mostly miking at 63,3 mms; cases fired in self-loaders may be longer. As an afterthough, neck length is of minor importance for performance, unless one be a benchrester. Far more important is the best seating depth of the bullet (distance from the lands). Shoot one lot of cases with 63 mms length and one with 64 mms, it won't make much of a difference for hunting purposes. What is important is that the neck be still long enough to hold a bullet firmly (once an occasional problem with the .300 Savage e.g., which only had a 5,60 mms neck). The 8 x 64 S has about 8,41 mms neck length, which is a bit more than the 8 x 57 IS. The 7mm Rem Mag, for comparison, has 6,89 mms neck length, the .280 has 8,66 mms. In any case, even a 63mm casing will hold a bullet firmly enough. Sincere regards, [This message has been edited by carcano91 (edited 02-02-2002).] | |||

WC, I happen to agree with Carcano and don't see where he was stating any of those claims you made against him. He comes across as a knowledgable person whereas you come across as a irritable know it all. The last time someone offered different views you took it as "venting". Sit back, take a prozac and accept that there are different approaches to things and try growing up. I do agree with Bear Claw totally. If I "had" to do a wildcat on a 8mm barrel, I would do it in a 9.3X64 Brenneke case and get something out of it. I don't do it as they are ultimately a waste of money and generally there is no market for it. As a casual user or hunter that doesn't have to figure into the picture until you want to get rid of it. And "getting rid of it" will be the proper term. Wildcats are tough to sell, the market is extremely limited and you never get any value out of them. | |||

Hey Carcano where can I get some data/photos of that 8.5x64? It looks like it might be very close to a 338-06. I hope the Germans moved the shoulder forward to create a larger boiler room. ------------------ [This message has been edited by Bear Claw (edited 02-03-2002).] | |||

It is the most sensible idea (shortening an 8 x 68 is self-defeating); the only other case, which is a rarity of its own, is the 10,75 x 68, from whence the 9,3 x 63 is derived. A rifle for this latter cartridge is apparently owned and used by one of the gentlemen here on the boards; as I recently learned.

I can go to the public range on weekends, and come home with a 5 gal pail full of once fired 30-06, and .270 brass, with a good bit of 7mm rem, and 300 win thrown in. | |||

I suppose "hard to find" is relative. I can find metric brass quite easily in my Midway (or Wideners, or Graf & Sons, or Sinclair) catalog. My telephone is also easy to find. The combination of the two will allow me to find metric brass on my front doorstep. Any brass (other than .22LR) is hard to find at my range, as most folks there are reloaders and keep their brass. | |||

Carcano, Yes I am interested. You can find quantities of once fired 9.3X64 brass? Guess you can, it is made there and sounds like it is a lot more common. Would appreciate any information and how I can acquire some. Chic [This message has been edited by Customstox (edited 02-06-2002).] | |||

Common since tells me the 8x64 will shoot circles around the 8mm-06 performance wise. I never met a wildcatter that took cost into consideration unless he was scribbing an article for some magazine... A wildcatter that takes cost into consideration is a walking, talking, breathing, oxymoron.... ------------------ | |||

Possibly I am missing out on something here because I don't know anything about the european designation for cartridges. The cartridge which came to mind for me is the 8mm Mauser, but perhaps that is already one of the designations mentioned. It is not the cartridge I would pick, but would seem to be a natural to fit the action with a minimum of work. | ||
one of us |
WJ I would go with an 8mmGibbs. This gets the most powder space from '06 case I think. I have a 1914 mauser so chambered and it seems about perfect cartridge for bore size. I got dies from RCBS about 25 yr. ago. I'm sure my cases hold 65+ gr. 4831. The drawback,if there is one, is the relatively short neck. This is not a big deal for me but others frown on it.Mark | |||
|
one of us |
Bruce, the 8mm Mauser is the 8 x 57 (otherwise known as the 7.9 x 57). After WWI to avoid the ban on military calibers, the manufacturers started chambering (and rechambering) the 8 x 60. It's just a little longer in the case. The 7 x 64 had been around for awhile, and they decided to open up the neck for an 8mm bullet, hence the 8 x 64. The 8mm-06 is basically a North American version of the 8 x 64. We've done this dance before, but in this neck of the woods -06 brass is way more available. And yes, you can buy factory loaded ammo (at least two sources) and correctly headstamped brass. Admittedly not from the big manufacturers, but it is available. As an aside, as 358Mark points out, the Gibbs case design pretty much maximises the -06 brass. My 8mm-06 is the Ackley Improved version, but I have a 7mm Gibbs I'm very happy with. Yes it does have a short neck, and some people will dislike that feature, so they should probably go for the regular 8mm-06 or the Ackly version. As for performance differances, as they (8mm-06 and 8 x 64)have almost identical case capacities, I would not expect any more variation between identical rifles then is the statistical norm. The improved versions will usually give improved performance. As an all around cartridge, it works very well, even better than the 30-06 (higher speed with heavier bullets). FWIW - Dan | |||

quote: Right. Performance of the 8 x 60 I/R/S is a bit better than the 8 x 57 I/R/S in case of the "normal" loads. However, the hotrod "Magnum" and "Magnum-Bombe" loads of the interwar years were definitely a step up.
quote: Uhhh...well... The 8 x 64 was introduced in 1912 by Wilhelm Brenneke als a military proposal; and indeed it was inspired either by the longer case of the .30-06 or by the excellent civilian German 9 x 63 M/88. The 7 x 64 (ever so popular) was introduced only later, in 1917.
